Viscosidad Cinemática

Acerca de Kinematic Viscosity Conversion

Kinematic viscosity es dynamic viscosity divided by fluid density—eso describes como rapido un/una fluid flows under el/la influence of gravity alone, without cualquier applied force. This fundamental property determines como quickly un/una fluid drains, como long eso takes un/una flow through un/una calibrated tube, y como eso behaves in gravity-driven flow situations. El/La kinematic viscosity directly measures que matters for gravity-fed lubrication sistemas y drainage aplicaciones.

El/La SI unidad es square metros per segundo (m²/s), pero centistokes (cSt) es el/la overwhelming practico estandar, especially for lubricants y petroleum products. Motor oil grades (SAE 5W-30, etc.) son defined by kinematic viscosity at estandar temperatures—100°C for el/la hot rating, -35°C for el/la cold (W) rating. El/La centistokes unidad persists porque eso produces convenient numeros: water es aproximadamente 1 cSt at 20°C, light oils son 10-50 cSt, y heavy lubricants son 100-500 cSt.

Our converter handles todo estandar kinematic viscosity unidades for lubrication engineering, petroleum refining, y fluid sistema design.

Common Kinematic Viscosity Conversions

Kinematic Viscosity Unidad Reference

Square metro per segundo (m²/s) – El/La SI unidad for kinematic viscosity. Impractically large for la mayoria fluids—water es aproximadamente 10⁻⁶ m²/s, requiring cientifico notation. Reserved for theoretical calculos y dimensional analysis. 1 m²/s = 10,000 Stokes = 1,000,000 cSt. Rarely usado in practico specifications.

Centistokes (cSt) – El/La dominant practico estandar for lubricants, petroleum products, y industrial fluids worldwide. 1 cSt = 1 mm²/s = 10⁻⁶ m²/s. SAE oil grades son defined by kinematic viscosity in cSt: SAE 30 es 9.3-12.5 cSt at 100°C, SAE 40 es 12.5-16.3 cSt. ASTM y ISO lubricant standards usar cSt exclusively. Water ≈ 1 cSt at 20°C proporciona un/una intuitive referencia point.

Stokes (St) – CGS unidad equal un/una 1 cm²/s = 100 cSt. Named after George Stokes. Less comun in modern practice pero still appears in older cientifico literature, algunos European referencias, y conversion tablas. 1 St = 0.0001 m²/s.

Square milimetro per segundo (mm²/s) – Numerically identical un/una centistokes (1 mm²/s = 1 cSt exactamente). Increasingly preferred in ISO standards y cientifico publications eso avoid non-SI unidades. Provides SI compatibility while maintaining el/la convenient scale of cSt.

Square pie per segundo (ft²/s) – US customary unidad occasionally found in older American engineering referencias. 1 ft²/s = 929 St = 92,903 cSt. Rarely usado in modern practice; la mayoria US lubricant specifications usar cSt.
